Given numbers are 170, 457, 399

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(170, 457) = 77690

GCD(170, 457) = ( 170 x 457 ) / 77690

= 170 / 457

= 170

Step2:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 170, 457, 399 is 1
